I average around 14-15 seconds with a PB of 9.79 Seconds. The key to getting better is not just practice, it is DELIBERATE practice. Just solving the cube a whole bunch of time will only get you so far. If you wish to get better, then you need to deliberately practice on specific things like look-ahead, finger tricks, optimising solutions etc.

[@dmr778810]

The last challenge is the _perfect_ example of all knowledge, and no practice. Because it's different, you're not used to it. "Shortcuts" such as looking for the white corner don't work the same because you need to remind yourself what your cross color is, especially if the color schemes are not standard setup, or even standard colors. An easier example of this is when you try to become color neutral, or even dual neutral. When you're used to white cross, and you do yellow cross, you can end up placing Red/Blue into the Red/Green slot because that's what you're used to.

[@softwarelivre2389]

I always solved my cube as color neutral for that very specific reason. I'm not fast, but I'm flexible.

[@krishkalra756]

Ive started to try and become dual neutral and it was fun to see jperm struggle as much I currently do

[@softwarelivre2389]

@@krishkalra756 I admit I have a preference for blue, red and orange. I rarely start with green, white or yellow for some reason. I think it is because I have a harder time finding those pieces due to lower contrast between them on my cube. Gotta practice that.

[@RootsThatRuin]

I actually think the last “bonus challenge” definitely demonstrates an important point that’s super relevant to this video: the first handful of challenges were all knowledge/zero practice, the first bonus challenge was very little knowledge/lots of practice, and the last bonus challenge was tons of knowledge AND tons of practice *except* the time you spent practicing on a normal cube to gain quick recognition was suddenly not useful. You couldn’t just transfer your recognition to the new color scheme. It demonstrates how important training your brain to recognize the color patterns on the cube is. How do you do that? Yep, you guessed it, practice! Really cool, informative video, thanks Dylan!

[@ImmortalKnightCubing]

For three sides challenge ,you can solve the cube normally till OLL , and then instead of one looking the pll,use the A perm algorithm by keeping the headlights on back so that you end up with any one of the U-perms, pretty sure that would have been way faster!

[@raininq3767]

That’s 2-Look PLL where you do 2 algorithms to solve PLL. The problem is, these two alga are quite long and recognition between the two does build up, which is why 1-Look PLL is better because it combines recognition and 1 algorithm of decent length, plus the algorithms can be adapted to your feel and solving, whereas 2-Look has fixed algorithms.

[@ImmortalKnightCubing]

@@raininq3767 yes I know that’s 2 looking, but the job is to just solve 3 sides ,so we just gotta do an APerm once from the correct position and stop the timer. Till OLL part , Dylan can easily do that in 6 or so seconds , and this in the worst case takes two or three seconds more , so he essentially would solve the cube(3 sides) in approximately 9 secs

[@matthijssmulders3432]

I think he deliberatly didn't think about it like this, because starting with normal CFOP kind of destroys the purpous of the video? But if you just wanted to do it as fast as possible I totally agree

Columns first seems like an ok method. Columns in 2 seconds, centers 0.5, edges 3 to 4, top layer alg 0.5. You would need a bit of practice to reach these but and they are complete guesses based on me trying slowly without actually looking at the method. For it to be effective you would need every pll skip from oll alg.

Got a 58 once and an average of 1:34 in 7 days using the beginner method. lucky random f2l cases randomly popping into place without deliberate construction also helped and solving the middle layer is fun when all the pieces needed to make the second layer whole, are already there but in the wrong spot is a joy to work at because I can look at the piece coming out and instantly realize which color it corresponded to. Using a Bluetooth cube like the i2,i3 really helped me understand cube notations and made it easier to learn algorithms by glancing at motion lines and reading cube notations

[@DeviatingVapors]

alt color schemes is what you should probably practice then. I have had a few cubes, and all have taught me what I know AND really what I don’t know. then I migrated to pushing myself to do every solve in a different start (color). shows very interesting patterns and color combinations (in the solve) sometimes. columns first. that’s a new one on me.

[@bilingualchad]

Not only do you mathematically take 0 sec to solve the corners, you actually take 0 sec to solve corners, because you solve them with the edges. That's why f2l+full oll+ full pll is faster than the beginner f2l (corners then edges)+2 look oll+2 look pll

[@LIA-52]

Bonus challenge 2: I do that in every practice session, because I have stickered my GAN12PE in a non standard way: white-blue, green-red, and yellow-orange. During practice I either grab that one, or my GTS3M, so I have to keep in mind which cube I am using, and not accidentally think about my other cube (which I may or may not have done a few times).

You know, the restriction was not to solve all the sides to complete 3, 4, or 5 sides. But you could still solve the cube entirely, and perform some kind of J perm, or T perm to mess up a few sides to have a faster time. Maybe solve all sides, but make a 2-swap of three top layer edges for 3 sides. For permutation only, maybe do a full solve, and make a superflip.

An idea for a challenge: go from an unsolved state to an only-double-turn-solvable state (so all opposite colors on both sides), and maybe to add a layer of complexity go to an only-double-turn-solvable state where at least one of the sides has a specific pattern on it

[@minjawee]

Hey J Perm, I’m relatively new to cubing but I had an idea for a competition. I’m not sure if its been done before or not. Nor do I know the likeliness of you even seeing my comments but here goes. The competition would be… Either a blind solve or a minimum inspection time to see who can solve the cube in the fewest moves. Everyone gets the same scramble and every round is a new (but same for everyone) scramble to see who can consistently solve in the least amount of moves possible. 1 try each round top times move to next round sorta like 64>32>16>8>4>2>1 elimination. Time could be used for tie breakers.

For 3 sides it should be super fast for you. Just solve it normally then for PLL just do a T perm or a Y Perm (unless the PLL is a T Perm or a Y Perm) so you force the corners to be solved and then it will probably be a U perm.
